Bond pair is simply a pair of electron which is being shared mutually between two atoms forming a chemical bond or in other words, it means the electron density lies in between two atoms.

Then if I have 210.1 g barium chloride with 45g potassium...how many grams of potassium chloride will I produce?

Katarina [22]

Answer:

85.8 g

Explanation:

The molar mass of BaCl₂ is 208.233 g/mol, so 210.1 g is about ...

210.1/208.233 ≈ 1.009 mol

The molar mass of K is about 39.089 g/mol, so 45 g is about ...

45/39.089 ≈ 1.1509 mol

The balanced equation seems to be ...

BaCl₂ + 2K ↔ 2KCl + Ba

This reaction requires 2 moles of potassium for each mole of barium chloride, so the available potassium limits the reaction. The result is as many moles of potassium chloride as there are moles of potassium.

The 1.1509 moles of KCl, at 74.551 g/mol will have a mass of about 85.8 g.

The reaction produces 85.8 g of KCl.

6) What types of atomic orbitals are in the third principal energy

Bumek [7]

Answer:

Types of atomic orbitals present in the third principal energy are s, p and d only .

Explanation:

OPTION A-: s and p atomic orbitals - these two orbitals are present in second principal energy level. Therefore , the option is incorrect.

 OPTION B-: p and d only - This option is wrong as there is no such principal level energy where , s atomic orbital is absent .

OPTION C-: s , p and d only -these orbitals are present in third principal energy level. The third major level of energy has one orbital, three orbitals of p, and five orbitals of d, each of which can contain up to 10 electrons. The third stage thus holds a maximum of 18 electrons. This option is correct .

OPTION D-: s , p, d and f only -There is also a f sublevel at the fourth and higher stages, containing seven f orbitals, which can accommodate up to 14 electrons at most. Therefore, up to 32 electrons will hold the fourth level: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. This option is incorrect .

Thus , the correct option is C (s , p and d only .)
